I agree. It is absurd. One could say there is a genetic relationship between Basque and Ainu, but not linguistic. Regarding the genetic relationship, it's fairly weak (Basques and Ainu are presumably genetically closer to each other, for example, than Basques are to people from southern India, or Ainu to Australian Aborigines). The relationship is this: Wells points to a common origin for Europeans and northern Asians/American Indians in Central Asia about 35,000 years ago (associated with a Y-chromosome lineage called M45). The Ainu might be a relic population of this ancestral group, as might the apparently extinct Paleo-American population to which the Kennewick and Spirit Cave men belonged. The Basques are a relic of the earliest European lineage to derive from the common Central Asian ancestor (the M173 lineage which I talked about in my earlier post.)

"OTOH, the Celtic languages are spoken by people who are genetically closer to the Basques than to the original Celtic speakers, so maybe the Basques adopted Basque from the first farmers to migrate into Spain.

Ryan and Pittman, in their book Noah's Flood (The Black Sea Flood 7,600 ya), speculate that there were hundreds of thousands of humans huddled around the (then) freshwater Black Sea. When the Black Sea flooded with saltwater (rising 6-12" a day) most of these people were simply able to walk away with whatever they could carry with them up the river valleys all across Europe...taking their language and farming culture with them.

I believe the Tocharians in China may also be refugees from this flood.(?)

The last I've seen, linguists have traced all the IE languages back to Anatolia...using mainly farming words.
